For the application process, the joint that requires sealing should be designed in a way that these do not lead to sealant stress of any kind. The joints should be thoroughly cleaned using an oil free solvent that can be applied onto the joints with a brush. Next, masking tapes should be applied on both the joint sides. These tapes are to be removed as soon as the bead is complete. Apply the sealant and once it dries, clean the surface. A sealant cartridge gun can be used for the process. Break the cartridge seal only before use. Follow this by tooling the joints in single continuous stroke and remove the masking tapes.
